Final answer:
Consent is obtained from a legally authorized representative when a client is found incapable. Informed consent and the principle of autonomy are important considerations when obtaining consent.
Step-by-step explanation:
If a client is found incapable of providing consent, consent is to be obtained from a legally authorized representative. In the case of children, parents can provide consent on their behalf. In other situations, a court-appointed guardian or a designated healthcare proxy may provide consent.
The principle of autonomy also plays a role in obtaining consent. In clinical settings, patients have the right to exercise self-determination in making decisions about their own healthcare. This includes the right to give or withhold consent for medical procedures or participation in clinical trials.
It is important to ensure that participants have been fully informed before obtaining their consent. Informed consent means providing relevant information about the study or procedure so that individuals can make an informed decision about whether to participate.
